Abstract: FIELD: shaping.SUBSTANCE: invention relates to a method for producing plastic pipes reinforced with carbon fibre. The method for producing plastic pipes with carbon fibre has the stages of: preparing an extrusion apparatus (100) provided with an apparatus (4) in the body (1) for creating an electric field between two annular and concentrically located electrodes (40, 41); introducing a composite material (10) when flowing through the annular gap into the gap (42) between both electrodes (40, 41), wherein the composite material (10) comprises polytetrafluoroethylene (PTFE) as the main material of the matrix and carbon fibres, creating an electric field and releasing the extruded plastic pipes through the outlet area (3) of the body (1), wherein the carbon fibres contained in the composite material are aligned with a high normal component to the axis of the extrusion apparatus due to the created electric field, so that the heat conductivity of plastic pipes in the direction of the fibres of more than 750 W/m*K is achieved.EFFECT: ensured production of highly efficient and chemically resistant tubular heat exchange systems from thin-walled (t=<1.5 mm) highly conductive carbon fibre pipes due to the targeted use of high anisotropic heat conductivity of ultra-high modulus carbon fibres (ρ=2.2 g/cm3; λ=1,200 W/m*K); due to the special orientation of the fibres with a high normal component to the axis of the pipe, high heat conductivity of the plastics reinforced with carbon fibres in the direction of the fibres and high strength, as well as rigidity of the pipes are achieved; due to the use of ultra-high-modulus fibres because of the negative coefficient of heat expansion (<-0.1*10-6/K) thereof, the heat expansion of the pipe is minimised, allowing for a significant reduction in the risk of longitudinal deflection of the pipes and leakage; additionally, the use of a thermoplastic polytetrafluoroethylene matrix leads to a significant reduction in the weight of the system, as well as to significant chemical resistance and resistance to medium loads.4 cl, 6 dwg
